SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1155 AM CDT SUN JUN 6 1999

A MODERATE RISK OF SEVERE WEATHER STILL EXISTS FOR MUCH OF CENTRAL
AND SOUTH CENTRAL MINNESOTA INTO WEST CENTRAL WISCONSIN THIS
AFTERNOON AND EVENING.  THE RISK OF SEVERE THUNDERSTORMS IS NOT
QUITE AS GREAT IN FAR WEST CENTRAL MINNESOTA.

A STRONG COLD FRONT HAS PUSHED INTO FAR WESTERN MINNESOTA FROM NEAR
MOORHEAD TO MORRIS TO MARSHALL.  THIS COLD FRONT WILL DRIFT INTO
CENTRAL MINNESOTA BY EARLY EVENING...AND THEN INTO WESTERN WISCONSIN
OVERNIGHT.

THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THE FRONT WITH SOME OF
THE STORMS BECOMING SEVERE. THE GREATEST THREAT OF SEVERE WEATHER IS
OVER CENTRAL INTO EASTERN MINNESOTA THIS AFTERNOON AND INTO WESTERN
WISCONSIN THIS EVENING.  THE MAIN THREAT OF SEVERE WEATHER WILL BE
LARGE HAIL AND DAMAGING WINDS.  ISOLATED TORNADOES ARE POSSIBLE AS
WELL.

SEVERE WEATHER SPOTTERS SHOULD BE PREPARED FOR ACTIVATION ACROSS THE
OUTLOOK AREA. PERSONS IN CENTRAL AND EASTERN MINNESOTA AND WESTERN
WISCONSIN SHOULD PAY CLOSE ATTENTION TO WEATHER CONDITIONS THROUGH
THIS EVENING...AND BE READY TO SEEK SHELTER SHOULD WARNINGS BE
NECESSARY.
